Pattern is a live kaleidoscope camera app for Android (package com.hugosoftware.pattern, version 1.0.0). It takes the pixels inside a small "core" square at the centre of the screen and mirrors, divides and spreads them across the whole display in real time using the device GPU, turning whatever the camera is pointed at into hypnotic symmetry. Features: 4 mirror modes (radial, grid, triangle, spiral), 6/8/12/16 segments, adjustable core size, colour hue control with automatic drift, auto-spin with speed control, a freeze button, photo and short video capture in 1:1 / 9:16 / 16:9, and a built-in on-device gallery where the user can view, share or delete their captures. The app is COMPLETELY FREE: there are no ads, no advertising SDKs, no subscriptions, no in-app purchases and no paid features. There are NO user accounts, no sign-up, no login and no user profiles. The app is English only. It is built with web technology (Capacitor/WebView) wrapped as a native Android app.
